The magnetic device T3 is configured to generate a magnetic force to the first magnetic element 27. When the first magnetic element 27 is moved toward the display panel 22 by the attraction of the magnetic force generated by the magnetic device T3, the movement element 26 is rotate to move the upper electrical connector 23 to the storage position.

In the embodiment, the magnetic device T3 may include a mounting frame T31 and a second magnetic element T32. The mounting frame T31 may be detachably disposed on the display device 20, and in contact with or adjacent to the display panel 22. The second magnetic element T32 may be movably disposed on the mounting frame T31, and may be located in the mounting frame T31.

When the upper electrical connector 23 is to be moved from the connection position to the storage position, as shown in FIG. 10, the magnetic device T3 can be mounted on the display device 20, and in contact with or adjacent to the display panel 22. Moreover, the second magnetic element T32 is located in the first position far from the display panel 22. When the second magnetic element T32 is far from the display panel 22, the magnetic force generated by the second magnetic element T32 to the first magnetic element 27 is less than the elastic force applied by the elastic element 25 to the upper electrical connector 23. Therefore, the upper electrical connector 23 is maintained at the connection position.

As shown in FIG. 11, when the second magnetic element T32 is moved to a second position that is adjacent to the display panel 22, the magnetic force generated by the second magnetic element T32 to the first magnetic element 27 is greater than the elastic force applied by the elastic element 25 to the upper electrical connector 23. Therefore, the movement element 26 may move the upper electrical connector 23 to the storage position.

As shown in FIG. 11, when the upper electrical connectors 23 a and 23 b is moved to the storage position, the fixing element T1 may be removed from the display device 20 b, the display device 20 b may be moved in the second direction D2 and removed from the fixing frame 10, the display device 20 a and the display device 20 c. Therefore, when the display device 20 b is damaged and needs to be repaired, it is not necessary to remove the display device 20 a and/or the display device 20 c, thereby improving the efficiency of repairing the display apparatus 1 and reducing the difficulty of repairing the display apparatus 1.

FIG. 12 is a perspective view of the display device 20 in accordance with the sixth embodiment of the present disclosure. FIG. 13 is a schematic view of the display apparatus 1 in accordance with the sixth embodiment of the present disclosure. In the embodiment, the upper electrical connector 23 and the lower electrical connector 24 may be cables. One end of the upper electrical connector 23 is connected to the top portion 211 of the housing 21, and the other end of the upper electrical connector 23 is connected to the rear side 216 of the housing 21.

In the embodiment, the upper electrical connector 23 may protrude over the top portion 211 of the housing 21, and the lower electrical connector 24 is located in the bottom portion 212 of the housing 21. When two display devices 20 are connected, the upper electrical connector 23 and the lower electrical connector 24 may have a function of alignment for aligning the two display devices 20.

As shown in FIG. 12 and FIG. 13, during assembly of the display apparatus 1, the display device 20 a may be affixed to the fixing frame 10 by the fixing element T1. Afterwards, a conductive glue M1 may be coated on the top portion 211 a of the display device 20 a. The display device 20 b may be placed on the display device 20 a, and the lower electrical connector 24 b of the display device 20 b is aligned with the upper electrical connector 23 a of the display device 20 a. The present disclosure does not particularly limit the coating position of the conductive glue M1, as long as the conductive glue M1 is disposed between the two display devices 20. In other words, in another embodiment, the conductive glue M1 may be coated on the bottom portion 212 b of the display device 20 b, and then the display device 20 b is placed on the display device 20 a.

After the lower electrical connector 24 b of the display device 20 b is aligned with the upper electrical connector 23 a of the display device 20 a, the display device 20 b can be easily aligned with the display device 20 a, and the lower electrical connector 24 b of the display device 20 b can correspond to or be connected to the upper electrical connector 23 a of the display device 20 a. In another embodiment, upper electrical connector 23 a is electrically connected to the lower electrical connector 24 b. In another embodiment, the upper electrical connector 23 a is adjacent to the lower electrical connector 24 b. At least a portion of the upper electrical connector 23 a overlaps the lower electrical connector 24 b in the first direction D1 or the second direction D2. Finally, the display device 20 b is affixed to the fixing frame 10 by the fixing element T1, and thus the assembly of the display device 20 b may be easily completed.

Afterwards, the conductive glue M1 may be coated on the top portion 211 b of the display device 20 b. The display device 20 c is placed on the display device 20 b, and the lower electrical connector 24 c of the display device 20 c is aligned with the upper electrical connector 23 b of the display device 20 b. The present disclosure does not particularly limit the coating position of the conductive glue M1, as long as the conductive glue M1 is disposed between the two display devices 20. In other words, in another embodiment, the conductive glue M1 may be coated on the bottom portion 212 c of the display device 20 c, and then the display device 20 c is placed on the display device 20 a.

After the lower electrical connector 24 c of the display device 20 c is aligned with the upper electrical connector 23 b of the display device 20 b, the display device 20 c can be easily aligned with the display device 20 b, and the lower electrical connector 24 c of the display device 20 c can correspond to or be connected to the upper electrical connector 23 b of the display device 20 b. In another embodiment, upper electrical connector 23 b is electrically connected to the lower electrical connector 24 c. In another embodiment, the upper electrical connector 23 b is adjacent to the lower electrical connector 24 c. At least a portion of the upper electrical connector 23 b overlaps the lower electrical connector 24 c in the first direction D1 or the second direction D2. Finally, the display device 20 c is affixed to the fixing frame 10 by the fixing element T1, and thus the assembly of the display device 20 c may be easily completed.

In the embodiment, the conductive glue M1 may be anisotropic conductive film (ACF). The upper electrical connector 23 and the lower electrical connector 24 of two adjacent display devices 20 can be finely electrically connected to each other in the first direction D1 by the conductive glue M1.

In the embodiment, the alignment between the display devices 20 can be easily performed by the upper electrical connector 23 and the lower electrical connector 24, so as to place the display panels 22 on a reference plane P1. Therefore, the assembly time of the display apparatus 1 may be reduced, and the integrated image displayed by the display apparatus 1 may be improved.

As shown in FIG. 13, when the display device 20 b is damaged and needs to be repaired, the fixing element T1 may be removed from the display device 20 b. Moreover, the display device 20 b can be moved and separated from the fixing frame 10, the display device 20 a and the display device 20 c in the second direction D2 by applying force or using the appropriate tool (such as a cutting knife). Therefore, when the display device 20 b is damaged and needs to be repaired, it is not necessary to remove the display device 20 a and/or the display device 20 c, thereby improving the efficiency of repairing the display apparatus 1 and reducing the difficulty of repairing the display apparatus 1.

In the embodiment, damage to the upper electrical connector 23 and/or the lower electrical connector 24 may occur during the removal of the display device 20 b. However, since the upper electrical connector 23 and/or the lower electrical connector 24 are attached to the outside of the housing 21, the replacement of the upper electrical connector 23 and/or the lower electrical connector 24 can be easily performed.

The disclosed features may be combined, modified, or replaced in any suitable manner in one or more disclosed embodiments, but are not limited to any particular embodiments.

In conclusion, during assembly of the display devices, the display apparatus of the present disclosure may not need additional connection lines to connect to the display devices 20, thereby reducing the complexity of assembling the display apparatus 1. Moreover, the display apparatus utilizes the limit mechanisms (such as the lower receiving groove, the upper electrical connector, and the connection element) between the display devices to align the display devices, thereby reducing the assembly time of the display apparatus 1. Moreover, when one of the display devices 20 is damaged, the damaged display device 20 may be directly removed, thereby improving the efficiency of repairing the display apparatus.
